The movement to end street harassment takes another giant leap forward today as an additional 11 Hollaback! sites launch internationally, adding to an already vibrant network of 34 sites across four continents. Each site is run by a team of local advocates who are deeply committed to working on-line and off-line to end street harassment in their communities.

“I decided to start a Hollaback! because I wanted to be a part of a collective of dedicated and passionate activists fighting to make the streets safe for women all over the world,” said Hollaback! Palo Alto Founder Viviana Arcia. The organization expected to only launch in five cities this year, but is now in 45 cities across 16 countries, with leaders speaking more than nine different languages — each with the same message: street harassment must be put to a stop. New locations include Bogota, Colombia; Boston, MA; San Luis Obispo, CA; Chennai, India; Dusseldorf, Germany; Minneapolis, MN; Montreal, Quebec; Palo Alto, CA; Portland, ME; Santiago, Chile; and Winnipeg, Canada.

“What we tend to forget is that preventing sexual harassment in the long run is about changing our attitudes, not just ensuring physical safety. This is where we come in with Hollaback!” said Hamsini Ravi, Project CoordinatorHollaback! Chennai.

Local Hollaback! site leaders run their local blogs and organize their communities through advocacy, community partnerships, and direct action. Site leaders are as diverse in their backgrounds as they are in their experiences of harassment. Hollaback! reports that 44% lesbian, gay, bisexual, and queer, 26% identify as people of color, 76% are under the age of 30, and 90% are women.

“Women and members of the LGBTQ community have always been taught that street harassment is inevitable and something that we need to accept, smile at, or ignore,” saysCara Courchesne, Director of Hollaback!Portland, Maine. “Hollaback! changes that storyline.”

Hollaback!’s international sites are already having an impact. In Querétaro, Mexico, site leaders have developed a workshop to promote cities free of harassment for all people. In the last two months, 600 young people have taken part. In Baltimore, MD, the site leader has organized several successful events, including an Anti-hate Prom and the Baltimore SlutWalk. In Croatia, site leaders are creating a survey that will allow them to collect data on street harassment that will then be used across the Hollaback! network, giving Hollaback! an ability to compare street harassment across cultures.
